This is because different genes are switched on or off in different cells.

For example, the cells which develop into red blood cells have the gene for making hemoglobin (the red, oxygen-carrying pigment) switched on. Other cells have this gene switched off.

No they don't


What kind of cells result from mitosis?

Mitosis results in two identical daughter cells, each with the same number of chromosomes as the parent cell. These daughter cells are genetically identical to each other and to the original parent cell.


Do all the cells of the body look alike?

no


Are all cells identical?

No, not all human cells are alike. Cells are specialized to do a certain job. For example, a nerve cell is different red blood cell because they have different jobs to do. They look different, have differentnumbers of certain organelles's, and they are not all alike.


Do all cells look the same?

No, all cells do not look the same. Cells can vary in size, shape, and function depending on their specific role in the body.


Do cells are genetically identical?

Cells form new cells with identical genetic composition through mitosis. This essentially involves the cell producing enough resources for two cells and then splitting it's membranes into two separate and distinct bodies.


What type of cell division does your body cells undergo And why can your body cells ONLY use this type of cell division?

Body cells undergo mitotic cell division so that each daughter cell is genetically identical to each parent cell and to all other body cells.


Would there be identical cells in an animal organ?

No all cells are different


Can DNA from one part of the body is similar to DNA of the other part in protein sequence structure morphology etc?

The DNA in all body cells should be identical.


Why don't all plant cells look the same?

By definition, all human cells are animal cells. Different cells look different from others, no matter the organism. A human nerve looks almost identical to a nerve from a chimp, but a human nerve looks nothing like a cell from a chimp's muscles.


What is a cell that forms in ferilization?

The first cell to form in fertilization is the zygote. The zygote undergoes cell reproduction in order to form a multicellular embryo, in which all of the cells are genetically identical to the zygote. All of the body cells in the new offspring will, in theory, be genetically identical, unless uncorrected mutations occur.


Mitosis occurs in what types of cells?

Mitosis occurs in all somatic cells of the body, which are any cell that is not a sex cell. It is the process by which a single cell divides to produce two genetically identical daughter cells with the same number of chromosomes.
